Hi Folks,

OK; I am in idiot mode today and mistakenly managed to hit
Tab which put me on the Send button by mistake - not once
but TWICE...; not used to this - duh...

We have a PC in our Graphic's Department that is having a
problem with the USB setup that controls a Xerox Color
Laser printer, an Epson Scanner and a Backpack CD Burner.
The PC is a Compaq Evo running Windows 2000 Pro. It is
completely up to date on all patches and Service Packs.

It started having problems and under Device Manager there
is a Yellow exclamation mark next to USB controller. So I
contacted Compaq and they had me try all kinds of stuff
including BIOS update, etc. and still no luck. They said
it was a software problem.

So I have been on the Windows support page searching for
Code 31 and got hits and tried various stuff with no luck.

On http://support.microsoft.com/default.aspx?scid=kb;en-
us;270008

It mentions to "Remove the Upperfilters and Lowerfilters
values completely from the following registry key:

1.
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
and I did that with no luck. There are a BUNCH of other
keys under this and the article mentions removing ALL of
them. Is it safe to do that or will that possibly corrupt
other things ?

Another article at
http://support.microsoft.com/default.aspx?scid=kb;en-
us;822368 mentions a hotfix that is from June of 2003 and
STILL has not been put in a Service Pack, etc ?? !!

Thanks for any help anyone can shed on this problem !
